Former Arsenal midfielder Liam Brady has called for Arsene Wenger to find a solution to the Gunners’ haphazard set-piece defending once and for all following their shock Champions League defeat to Olympiakos.

Manager Wenger has come under heavy criticism for his failure to sign an outfield player during the summer transfer window, with fans calling for a top class striker they believe will make the Gunners title challengers once again.

“We don’t have a problem in the forward area, not as much as people like to make out,” the FA Cup winner, and two-time Serie A winner with Juventus, told the Alan Brazil Sports Breakfast.

“Theo will play. He scored again last night and did really well for Sanchez’s goal.

“It think our defending, especially in set pieces, is where we really need to get better.

“We dominated the game, but we defended poorly from set-pieces and it cost us dearly.

“We lost a goal at Zagreb and two goals against Olympiakos to set-pieces. The first goal was bad last night, the ball coming into the box and players not really knowing what’s going on. The marking and concentration has got to be a lot better.

“If we get these things right the results will be more consistent and we won’t have this up and down situation we’re having at the moment.”

Having lost their Champions League opener at Dynamo Zagreb, a second successive defeat in Europe leaves Arsenal’s chances of progression hanging by a thread.

However, Brady believes spirited performances against group opponents Bayern Munich in the past gives the side a glimmer of hope.

He added: “It was a shock, but what can you do? We have to dust ourselves down and start again and somehow rescue the situation in the group.

“If we get six points in the next games against Zagreb and Olympiakos, we’ll have to try and get something from the Bayern game, but we’ve done it before against them.”
